I'm using 3.9-final-7067 image. Without DejaVu fonts GUI works much  
better, but it still seems to be very heavy for my machine (for  
example, scrolling of the "Changes that have been done in 3.9" window  
gives 100% CPU load).

Thanks,
Aleksandr

The Squeak mouse logo - with the eyes which follow the cursor - takes
quite a bit of CPU resource. Making it smaller with the yellow halo
handle, or indeed removing it completely will reduce the CPU load
considerably.

Thanks, but it seems not to be the case: there is not such mouse  
keeper in the Squeak I have.
But it reminds me the old anecdote, when a doctor asks the patient if  
he smokes: "No, I don't", - "It's a pity, you could try to drop it  
then". :)
